Thank you for reporting this issue. gRPC now requires Go version 1.22.7 or higher, as specified in here

grpc-go/go.mod

Line 3 in 1418e5e

go 1.22.7

Please update your Go installation to resolve this. If the issue persists, please let us know, and we’ll be happy to assist further.

It would be helpful if there was a place that could introduce the minimum supported Go versions for each version of gRPC since it's not very convenient to upgrade Go version for some older programs.

[eshitachandwani]

The minimum go version for each version of gRPC is mentioned in the go.mod file for each version. For [email protected], the minimum supported version is go 1.21 mentioned here:

grpc-go/go.mod

Line 3 in a75eb1e

go 1.21

@sh1yu gRPC promises to support till any of the last two go releases. See https://github.com/grpc/grpc-go?tab=readme-ov-file#prerequisites
